Abstract

The last twenty five years have seen significant advances in the technology and theoretical models associated with the use of piston gauges for the measurement of both pneumatic and hydraulic pressure. Most notably, the incorporation of computers and advanced electronics into commercial piston gauge systems has led to entirely new ways in which the basic piston gauge concept is used for pressure generation and measurement. Equally important, imporvements in materials and manufacturing technologies have resulted in instruments of simpler design with superior pertormance over broader operating pressure ranges. For instance, the upper end of pneumatic pressure operation has been extended considerably, to over 100 MPa, and dydraulic piston gauges of simple design now operate to over 500 MPa. The advent of analytical techniques such as finite element analysis and related computer modeling has led to improved understanding and design of piston gauges. Pneumatic piston gauges of increased diameters are now used as primary standards in some laboratories at levels of uncertainty previously associated only with the use of mercury manometers. This chapter will describe these and other recent advances.
